JOHN C. SCALES, OF CHICAGO, ILLINOIS.

Specification forming part of Letters Patent No. 208,338, datedSeptember 24, 1878 application filed August 6, 1878.

To all whom it may concern Be it known that I, JOHN C. SCALES, of thecity of Chicago, Cook county, State of Illinois, have invented new anduseful Improvements in Receptacles for Articles to be Screened, of whichthe following is a full description, reference being had to theaccompanying drawing, in which- Figure 1 is a longitudinal verticalsection; Fig. 2 a top or plan view, with the lid or cover open.

The object of this invention is to provide a receptacle for thereception of articles to be screened or separated, so arranged andconstructed as that the article can be deposited therein and operatedupon without the liability of the smaller particles or dust to be blownor carried away; and its nature consists in providing a box orreceptacle with an inclined chute or partition, with which a door orstop comes in contact, so as to form an upper and lower compartment,communicating with each other; in providing a latch or catch for holdingthe stop in position when required; and in providing a rod or stem soarranged as to operate the holding-catch by the closing of the lid.

In the drawings, A represents the box or receptacle; B, the inclinedchute or partition; C, the stop or door; D, the locking-latch E, thedisengaging-rod; F, the lid or cover; a, the pivot of the latch D; b,the opening in which D is located; 0, the ring or support for the upperend of E.

The receptacle A may be of any desired size, and may be made of wood orother suitable material. The inclined chute B may be made of wood or ofwire fabric, so as to form a screen, or of other suitable material, andextends from the top of the [box or receptacle toward the bottom,leaving a space between its lower end and the end and bottom of the box,as shown in Fig. 1.

The door or stop C is pivoted or hinged to the sides of the box A, asshown at c, or is hinged in any other suitable manner, and, as shown,its lower end comes in contact with the lower end of the partition orchute B, so that when the flap or stop C is hanging perpendicular, ornearly so, it will be in contact with the chute, against which it isheld by the engagement of the inner end of the pivoted latch or lever Dwith the face of the stop, which catch D is pivoted by the rod or pin ain the opening b, suitably formed in the side of the box A, and is to beso arranged as to operate to hold the stop C against the chute B whenthe lid of the receptacle is open, but leave it free to swing or moveaway therefrom when the lid F is closed, which operation isautomatically performed in the form of device shown, by means of the rodor stem E, the lower end of which is connected with the outer end of thelever or catch D, and its upper end passes through the ring or support0, and proj ects above the top of the box or receptacle A when the lidis open and the lever or catch D is holding the stop C in contact withthe chute or partition B. The lid F, which may be of any suitablematerial and construction, hinged to the box in any suitable manner toallow its free end to engage with the projecting end of E, acts, whenshut down or closed, by striking the end of E to operate the catch D.

The door or stop C might be arranged to come in contact with the upperface of the incline B at some point on such face other than the endthereof, in which case the lever or catch D may be lengthened so as toengage with and operate the stop or a catch might be arranged to engagewith each side of the flap or stop and hold it in place, such catchesbeing suitably located and pivoted in the sides of the box A for thispurpose, and operated by rods similar to the rods E, or in some othersuitable manner.

The stop C may be made in two sections,

the upper section being stationary and secured to the sides of the box,and the lower section being hinged thereto so as to swing or such stopmight be arranged to slide vertically up and down in suitable grooves orguideways, the inner end of the lever or catch D being secured thereto,and operating to raise and lower the stop.

In use, the material to be operated upon is deposited in the box orreceptacle above the incline B, the lid F being opened for this purpose,and is held in this upper compartment by reason of the stop C being 1ncontact with the inclined chute or partition B. As the lid F is closed,it will strike the end of the rod E, depressing the rod and the outerend of the lever or catch D, disengaging the inner end of the lever orcatch from its engagement with the stop 0, when a swinging stop is used,so that the material contained in the upper compartment will open thestop and pass into the lower compartment.

By this arrangement the material can be deposited in the box orreceptacle in such manner as to prevent the small particles from beingblown around; for when deposited in the lower compartment, as abovedescribed, the receptacle will be closed, and none of the material canthen escape into the air.

The lower compartment of the box or receptacle is to be provided withsuitable closed openings to remove the contents, and with screening orsifting devices arranged therein for separating the particles but assuch openin gs and screens may be of any of the wellknown forms andarrangements, they are neither shown nor described.

The essential feature of my invention consists in the employment of astop or door to prevent the material from descending to the lowercompartment until the box or receptacle is closed, and, preferably, thisstop is arranged so as to operate automatically on pins 0 to allow thematerial to escape from the upper to the lower compartment as the lid isclosed.

Other devices than the lock D and its operating-rod E, either operatedby the lid or some other means, might be used to open the stop or door0.

What I claim as new, and desire to secure by Letters Patent, is-

The box A, provided with the inclined chute or partition B, flap or stopG, and retainingcatch D, in combination with the rod E and cover F,substantially as and for the purposes specified.
